PACKING-BOX.

Specification of Letters Patent.

Patented Oct. 21, 1913.

Application filed January 27, 1912. Serial No. 673,785.

The present invention relates to improvements in packing boxes.

In carrying out my invention it is my purpose to produce a packingbox or journal which is primarily intended for use in connection with the shaft that is employed upon fan pumps for paper mills, but which. is of course, susceptible for other uses, the device being of an extremely simple construction being so constructed as to be readily applicable to the shaft or to the casing of the fan and which provides a packing ring having adjustable means whereby the said ring as well as the packing may be fed or forced against the shaft as occasion requires.

Nith the above objects in view and others of a similar nature, the invention resides in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

In the drawing, Figure 1 is a side elevation of a fan pump provided with the im provement, parts being broken away. Fig. 2 is a transverse sectional view taken upon the line 22 of Fig. 1. Fig. 3 is a longitudinal sectional view taken upon the line 33 of Fig. 2. Fig. & is a perspective View of one of the sections of the boxing showing the ring in position there-on. Fig. 5 is a similar view of the ring sections.

Referring now to the drawings in detail the numeral 1 designates a fan pump, 2 the fan casing, 3 the shaft for the fan and at the ball in the shaft. In the present instance the fan frame is provided with a journal or packing box which may be generally designated by the numeral 6. The packing box or journal comprises a pair of sections designated respectively by the numerals 7 and 8. Each of these members are centrally pro vided with a semi-cylindrical depression 9, and the said members below the depressions are provided with openings for the reception of bolts or analogous devices whereby the said sections are secured to the fan casing. Each of the sections 7 and 8 have horizontally straight faces, the same being extended a distance beyond the semi-cylindrical depressions and being formed with offsets or ring bears against the lips having openings which are adapted to receive retaining elements such as nuts and bolts, whereby the sections are sustained one upon the other.

The semi-cylindrical depressions are adapted to receive a packing of suitable bearing material, such as Babbitt metal, and each of the sections are further provided withtransversely arranged substantially l.- shaped recesses which are adapted to receive a cross sectional L-shaped ring member 10.

The recesses are of a greater area thanthe ring so that the offset portion of the said bearing metal, for a purpose which will presentlybe set forth. The ring 10 is preferably constructed of a pair of members, the same being secured to gether through the medium of removable elements such as screws 12, which are illustrated in the drawings. These screws, however, are not adapted to force the ring sections tightly into engagement with each other, but merely serve as means whereby the said ring sections are sustained in proper relation, one with the other.

One of the sections of the boxing is provided with a threaded orifice, the same communicating with the L-shaped depression or recess of the said section, and this threaded orifice is adapted to receive a threaded plug 13, the same bearing against the ring sections and adapted, when the said plug is actuated to compress the sections to force the bearing material against the shaft. One or both of the said sections may be further provided with openings, which also communicate with the substantially L-shaped depressions, these openings 14:, being adapted to serve as passages for a lubricant which is delivered to the ring sections. The openings 1a are normally closed, through the medium of suitable threaded plugs 15, and from the above description taken in connection with the drawings it will be noted that the device may be adjustable to various sizes of shafts and that the application of the same to the shaft will result in a great saving of stock in the paper mill as well as the saving of packing and the labor attached thereto.

Having thus described the invention, what I claim is:

1. A packing box for the purpose set forth comprising a pair of sections, each of said sections being formed with semi-cylindrical depressed portions for the reception of a shaft, means for securing the sections together and upon the shaft, packing members for the semi-cylindrical depressions, the packing box being provided with a substantially L-shaped depression, the packing members being also provided with substantially L-shaped flanges which are adapted to be received within the depressions, a cross sectional L-shaped packing ring engaging within the depressions provided by the packing members, said ring comprising a plurality of sections and means for compressing the sections to bring the packing elements toward the shaft. o

2. A packing box for the purpose set forth embodying a pair of removably connected members, means for connecting the members, means for attaching the members to a support, each of said members beingpro: vided with a semi-cylindrical depression, each of said members being further provided with semi-cylindrical grooves which register with the depressions, packing members within the grooves and the depressions, said packing members having their portions within the depressions provided with substantially L-shaped openings, a flanged ring engaging within the said openings and contacting the packing members, the said ring comprising a plurality of sections, means for loosely connecting the sections, 'means for compressing the sections one toward the other for regulating the packing elements, and means whereby a lubricant may be fed to the ring and to the packing elements. 7

In testimony whereof I afiix my signature in presence of two witnesses.
